'Heavy' in the Bible

for they bind together burdens heavy and grievous to be borne, and lay upon the shoulders of men, but with their finger they will not move them.

And having taken Peter, and the two sons of Zebedee, he began to be sorrowful, and to be very heavy;

and having come, he findeth them again sleeping, for their eyes were heavy.

and he taketh Peter, and James, and John with him, and began to be amazed, and to be very heavy,

and having returned, he found them again sleeping, for their eyes were heavy, and they had not known what they might answer him.

but Peter and those with him were heavy with sleep, and having waked, they saw his glory, and the two men standing with him.
